SCOPE, an acronym for Supervisory Control Of Program Execution, was the name used by the Control Data Corporation for a number of operating system projects in the 1960s.
SCOPE for the CDC 3000 series 
SCOPE for the CDC 6000 series 
This operating system was based on the original Chippewa Operating System. In the early 1970s, it was renamed NOS/BE for the CDC Cyber machines. The SCOPE operating system is a file-oriented system using mass storage, random access devices. It was designed to make use of all capabilities of CDC 6000 computer systems and exploits fully the multiple-operating modes of all segments of the computer. Main tasks of SCOPE are controlling job execution, storage assignment, performing segment and overlay loading. Its features include comprehensive input/output functions and library maintenance routines. The dayfile chronologically records all jobs run and any problems encountered. To aid debugging, dumps and memory maps are available. Under control of SCOPE, a variety of assemblers (COMPASS), compilers (ALGOL, FORTRAN, COBOL), and utility programs (SORT/MERGE, PERT/TIME, EXPORT/IMPORT, RESPOND, SIMSCRIPT, APT, OPTIMA etc.) may be operated. The computer emulation community has made repeated attempts to recover and preserve this software without success.
